A solution contains 0.00245 M HCl. Determine the [H3O+] for the solution.

Question

points Determine the [OH-]

Answer 1

Since HCl is a strong acid (meaning it ionizes 100%), then (H^+) = (HCl).
If you want to know OH and you have H^+, use
(H^+)(OH^-) = Kw = 1E-14

Answer 2

Thamks! How do I determine the pH value of this solution?

Answer 3

Do I use: pH= -log[h30+]

Answer 4

yes
